Application filed April 20, 1925, Serial No. 24 535, and in Czechoslovakia April 0,1 24,

This invention relates to Searchlight supporting or suspension devices and particularly, to devices for searchlig'hts usedln dethe present invention is to provide an improved supporting or suspension device for causing an aircraft fly-. ing in darkness to be easily and quickly caught in the beam of the Searchlight.

v 6 The main objectof ing or suspension device in accordance with the present invention is constructed with freedom of adjustment around a plurality of axes related to each other in a particular manner as hereinafter more fully described.

More particularly stated the device comprises parts angularly adjustable about five axes certain of which are at right angles to others. Several embodiments of the invention are illustrated in the accompanyingdrawings in which Figure 1 is a schematic representation or diagram illustrating the principle on which the present invention is founded.

Figure 2 is a combinedelevation and part plan of one embodiment of the 5-axis suspen- .sion device.

Figure 31s a combined elevation and part plan of a modified embodiment. Figure 4 is an elevation'of a further modi- 'fication.

Figures 5 and 6 are combined'elevations I and part plans of two still further modifications. r a V e 35 Referring first to Figure 1 it isto be observed that during the fli ht of an aircraft L in the straight line M- the direction .of flight determines with the position S of the searchlig'ht a "plane ABCD. The relative 40 situation ofthis plane to the position of the Searchlight is given by the horizontal angle B and by the vertical angle (1, having regardto the main directions or axes in space OX, OY and OZ. The direction of flight can be ascertained by means of an apparatus which registers the angles a and ,8 by recording sound waves and magnetic waves. If the axis of rotation of'the Searchlight is brought into a position perpendicular to the plane ABGD, then the beam, of the searchlight can be maintained on the aircraft no matter what is its height, speed or distance fromthe Searchlight. In order to obtain the perpendicular position of the axis With the above object in view the support below said joint. 7

of. rotation relatively to the plane ABCD, four additional axes of angular movement are'provided and so disposed that two-adacent axes are always situated perpendicularly with respect to each other. These four, axes form in conjunction with the axis of tilt of the searchlighta 5-axis suspension 7 or supporting device inconformity with the connecting axis 3. The axis 1-1 corresponds to the line C-D of the plane ABCD of Figure 1. The axis 2-2 corresponds to the line S-E at right angles to 0-D. The position of axis 3 is determined by the horizontal. angle ,8 and that of the axis 4-4 and 4-4, 5-5, connected through a common by the vertical angle a; 5-5 is the axis of tilt of the actual searchlight.

' The device according tov the modification illustrated'in Figure 3 comprises a Cardan joint 1-1, 2-2 connected with a 3-axis are rangement'having the axes 3,4, 5-5, located V In Figure 4 a 3-axis arrangement having thela'xes 1, 2-2, 3, is disposed above a Cardan joint having the'axes 4-4, 5-5. I

In Figure 5 a modification is shown, comor other suitable mechanism around optional axes, for instance 1-1 and 2-2 or 1-2 and l Figure 6 illustrates a still further inodiprising a 3-axis arrangment having axes 3, 7

The carriage 0 is itself mounted for rotation about an axis 3 and the whole apparatus is mounted upon. a tiltable' platform d which maybe set in position by means of the hemispherical bearmg the three screws f.
